Polytetrafluoroethylene　fibre　was　grafted　with　acrylic　acid　to　form　an　effective　ligand,　which　coordinated　with　Fe(III)　ions　to　prepare　an　Fe(III)-grafted　polytetrafluoroethylene　fibre　complex.　The　photoassisted　degradation　of　a　typical　azo　dye,　CI　Reactive　Red　195,　using　the　Fe(III)-grafted　polytetrafluoroethylene　fibre　complex　as　a　novel　heterogeneous　Fenton　catalyst　in　a　wide　pH　range　of　3-9　was　investigated.　In　order　to　achieve　better　degradation　in　a　higher　pH　range,　the　effect　of　Fe　content,　incorporation　of　Cu(II)　ions　and　UV　light　irradiation　on　dye　degradation　was　also　examined.　The　results　indicated　that　dye　degradation　was　effective　in　the　presence　of　the　Fe(III)-grafted　polytetrafluoroethylene　fibre　complex.　Fast　degradation　of　the　dye　can　take　place　in　an　acidic　environment.　Increasing　the　Fe　content　or　incorporating　Cu(II)　ions　can　significantly　accelerate　dye　degradation,　and　UV　light　irradiation　is　much　more　effective　than　visible　light　irradiation　in　a　higher　pH　range,　especially　in　the　alkaline　pH　range.
